As part of our ongoing documentation effort at the National Air and Space Museum, recent photographs of the Maurer 70mm cameras used during Gemini IX to XII have raised a few questions. I've found very little documentation about these cameras, other than the experiments to which they were assigned.

In particular, I'm hoping somebody here might know why there was a CO2 cartridge used in the film magazine. I've spoken to some photographers at the Museum, and the most common uses for those (cleaning and sensor noise control) don't seem like logical applications here. I have plenty of high resolution photos I could provide that might stir some thoughts.

Thanks folks!

The purpose of the CO2 cartridge was to release gas to press the film against the plate at the focal plane at the moment of exposure to eliminate any curl of the film.
